ROOF COVERING.

Application filed January 11,1922. Serial No. 528,582.

To all whom it may concern:

Be it known that I, No MAN'P. HARSH- BERGER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Roof Coverings, of which the following is a specification.

This invention relates to roof covering and has for its object'the production of suitable sheets or strips of roofing material so formed as to produce, when properly laid on the roof, a very effective protection from the weather, and also a very pleasing appearance. The individual strips of which the roofing is formed are so shaped as to be suitable for covering the roof in various ways, so that they may be laid to suit the particular case, either with reference to greater protection,'or with reference to a more p ap earance, as may be desired.

f the accompanying drawings Fig. 1 1s a plan view of an individual strip of roof covering Whichembod'ies the features of my inventien yFigs. 2, '3, 4, and 5, are plan views of the various ways in which the strips may be laid to suitably cover the roof; and Fig. 6 is a sectional view along the line 66 of Fig. 1.

The strips of roofing material indicated in Fi 1 may be composed of any suitable material such as felt, with a coating of asphalt and slate thereon, and they may be of any suitable length or width. Each of the strips has a plurality of flat body portions 10. The strips may consist of asmany of these body portions as may be desired. I prefer three of such portions in. each strip. The strip also consists of inclined closed folds 11 between the body portions, the folds to be any suitable width, and at any suitable angle; but I prefer the angle 12 to be in the neighborhood of 30, so as to produce a diamond shaped a pearance. At eachend of the strip a closed alf fold 13 is formed, the end half folds being on opposite sides of the strip.

With individual strips of this construetion it will be seen that the roof may be covered in man difierent ways, for example, as is indicated y the various Figures 2 to 5. In eneral, in laying the strips each strip is fapped upon the adjacent lower strip, so that the rain will flow downwardly without leaking; and, in order to form long or con'-' tinuous strips, a fold 13 is laid with its'ed e abuttin against the edge of a fold 14, t e two hai folds thus forming an entire fold easing equivalent toione of the folds 11. The strips may be lapped on the adjacent strips as much as may be desired; and the folds of one strip may be staggered or not, as desired, with reference to the folds of the other strips; and they abut against the folds of the adjacent strips, or may be spacedtherefrom.

In Fig. 2, which shows my preferred form of laying the strips, the long axis of each triangular shaped body portion is laid parallel with the peak or eaves 19 of the roof. This causes the strips to be inclined with the roof as is indicated. The edges of the roof may be filled in by properly formed strip portions 15, which are similar to the strips, except that they have an edge out off which othgrwise would project over the edge of the roo In case of Fig. 3, the strips are also inclined to the edges of the roof, but the short axis of each diamond shaped body portion is laid substantially parallel with the eaves 19 of the roof, thus forming in appearance, a row of diamond shaped portions extending parallel with the ends-of the roof. In case of Figs. 4 and 5, the strips themselves are laid parallel with the eaves, having corners 16 or 17 which may be allowed to project, or

may be cut as even with the edge of the roof, as is desired. It will beseen that the various methods of laying the strips present different appearances, and it is evident, ways of laying strips, other than those indicated, are entirely practical.

It will be noticed that in Fig. 2 the exposed edges of the folds arefacing downwardly, so that when viewed from below the edge is plainly visible, thus adding to the appearance, and at the same. time preventing water from flowing into the folds.

If a smoother looking surface is desired the exposed fold edges may face upwardly, as in Fig. 4, If it is desired to exposethe edges from a certain direction, the strips may be laid as in Fig. 3, in which the edges face to the right;-or, if an exposure of the edges from all directionsis desired, the strips Tr y be laid as in Fi 5, with the'edges of the alternate rows 0 strips facing in one direction and the other edges facing in the opposite direction. I

With roofing material of this nature, un- 13d" less the strips are unduly thick, thereis a tendency for theexposed corners toibowupwardly, or the entire strip or portions thereof may buckle upwardly attimes. To eliminate this danger I provide locking pieces 20 which are short narrow strips, and may be of the same material as the roofing itself, or otherwise. These pieces are placed, as indicated, with their edges in the adjacent folds; so that the locking piece is held down by the portion which is in the lower fold, and the other portion of the locking piece holds 'down the upper fold, thus eliminating the probability of the upper fold bowing upwardly. In manufacturing the strips each locking piece is permanently fixed in one of the folds.

I claim as my invention 2 l. A roof covering comprising strips of sheet-shaped material, this strips running substantially parallel with each other and each strip lapping on the adjacent lower strip, each of said strips having inclined folds therein, the folds of each strip being staggered with reference to the adjacent strips.

2. In a roof covering two strips or sheeting, each of the strips having inclined folds therein, one of the strips being aligned with and being a continuation of't'he other strip, the adjacent ends of the said two strips abutting together and forming the central portion of a fold.

4. A roof coveringcomprising strips ofsheet-shaped material, each of said stripe having inclined folds therein, the strips running substantially parallel with each otherand each strip lapping on the adjacent strip with the edges of its folds abutting against the edges of the adjacent strip, and a locking piece positioned in each pair of abutting folds.

5. An article of manufacture comprising a strip of roofing'material having a plurality of inclined folds, and having its edge offset at each fold.

6. A roof covering comprising strips of sheet-shaped material, the strips running substantially parallel with each other, and each strip lapping on the adjacent strip, each of said strips having inclined folds therein,

and the edges of the strips being offset at each of the folds.
